ABSTRACT:
A firearm having a hammer, firing pin, and trigger, and a movable firing block interposed between the firing pin and the hammer to actuate the firing pin when the hammer falls on it. The firing block is held in position by the trigger only when pressed, and the hammer fails to contact the firing block should it accidentally fall without the trigger being pressed.
The hammer upon being cocked pushes the firing block up into firing position. When the trigger is pulled, a firing block stop moves forwardly and prevents the firing block from dropping. The means on the hammer that pushed the firing block up is biassed to retract when the hammer falls, so that the firing action is completely dependent on the trigger.
